Here are two unrelated stories.
According to AP (via Yahoo), NASA will announce later this week that it will not have the funds needed to find at least 90 percent of the estimated 20,000 potentially hazardous asteroids and comets by 2020. Congress requested in 2005 that NASA come up with a plan to do this. The cost would be about $1 billion, and I guess NASA is a little short.
Fox reported yesterday that the number of billionaires in the world rose by 102 to a record 793 over the past year, with combined wealth of $2.6 trillion.
So here's an idea: Why don't one or two of you 793 billionaires step up to the plate and get this little asteroid hunting program going? Just as a way to protect your Earth-based investments.
